Bandcast is a mobile web application that utilizes Twilio to facilitate social networking among festival-goers at Lollapalooza, allowing users to send status updates, tips, and private messages, while filtering out non-festival-related noise. The app was created by Elenor Collings in response to the HackLolla competition's event API, aiming to help fans make the most of their Lollapalooza experience. Using Twilio, Bandcast provides an alternative check-in mechanism for users when data networks are overloaded, and has been praised for its ease of use and integration with Twilio's PHP Library. Elenor plans to expand Bandcast to other events and platforms, porting it to native apps for iPhone and Android in the future.
